CN2489983Y - Angle square with structure for changing angle - Google Patents

Abstract

The utility model relates to an angle square with structure for changing angle, belonging to device used for measuring work piece and drawing line. The utility model comprises a standard seat 1, an angle ruler 2 and a positioning bolt 3. One end of the standard seat and one end of the angle ruler are both provided with a positioning hole. The utility model is characterized in that a radial scale is arranged on the surface of the angle ruler taking the positioning hole as center; a standard line 5 is arranged on the end surface which is corresponding to the standard seat and the upper scale of the angle ruler; and the angle ruler is inserted into an end groove of the standard seat positioning hole, and is fastened by a positioning bolt. The angle ruler can rotate taking the bolt as center by only slightly screwing off the bolt, while the angle ruler can be positioned by screwing down the bolt to form an angle ruler with different angles. The utility model is suitable to be used for measuring various angles and drawing line. Besides, the utility model has the advantages of simple structure and low production cost.

Description

The variable angle wide seating square

Technical field

The utility model relates to the instrument of a kind of workpiece calibration, line, particularly a kind of angle square

Background technology

Known 45 degree, an angle of 90 degrees chi widely use in work posts such as pincers worker, but exist a lot of defectives in actual use, and limitation is big.At first be that everyone need be equipped with two angle squares, secondly expense is big, in use has inconvenience, once (this often runs in work posts such as pincers worker, carpenter and decorations) can't measure and rule when running into the angles line of non-45 degree, 90 degree, original setting-out way commonly used solves, and gets half the result with twice the effort.And existing universal protractor though it can be measured in 360 degree scopes, can only take measurement of an angle, and can not be used for line in work posts such as pincers worker, sheet metal, carpenter, and in addition, because of it is the fine measuring instrument of 0 grade or 00 class precision, its price is also very expensive.

Summary of the invention

The technical problems to be solved in the utility model is: just can measure, rule with an angle square any degree angle, and simple in structure, cost of manufacture is low.

This variable angle wide seating square comprises reference seat, bevel protractor, dog screw, reference seat one end and bevel protractor one end all have locating hole, it is characterized in that reference seat location nose end has groove, in the nose end insertion groove of bevel protractor location, be fastenedly connected by two locating holes by dog screw, be that the center has radial scale with the locating hole on the bevel protractor face, the reference seat end face corresponding with the bevel protractor high scale has datum line.The variable angle wide seating square of this structure, as long as turn on screw a little, bevel protractor can screw be that rotate at the center just, tightens screw and can locate, and forms the angle square of different angles, can measure, rule any degree angle, and simple in structure, cost of manufacture is low.

The specific embodiment

Present embodiment variable angle wide seating square comprises reference seat 1, bevel protractor 2, dog screw 3, reference seat 1 one ends and bevel protractor 2 one ends all have locating hole, reference seat 1 location nose end has groove, the bottom surface of groove becomes miter angle with the reference seat base, in the bevel protractor 2 location nose end insertion grooves, be fastenedly connected by two locating holes by dog screw 3, it is that the center has radial scale 4 that 2 of bevel protractors are gone up with the locating hole, reference seat 1 and bevel protractor high scale 4 corresponding end faces have datum line 5, the bevel protractor high scale is 9 to 0 to 9, and every little lattice are 5 degree, and every big lattice are 10 degree, when datum line on the reference seat 5 alignd with 0 graduation mark on the bevel protractor, bevel protractor 2 became an angle of 90 degrees just with reference seat 1.Such angle square can be measured, rule 0 degree to any degree angle in the 135 degree scopes.

Claims (2)

1, variable angle wide seating square, comprise reference seat (1), bevel protractor (2), dog screw (3), reference seat one end and bevel protractor one end all have locating hole, it is characterized in that reference seat location nose end has groove, in the nose end insertion groove of bevel protractor location, and be fastenedly connected by two locating holes by dog screw (3), be that the center has radial scale (4) with the locating hole on bevel protractor (2) face, reference seat (1) end face corresponding with bevel protractor high scale (4) has datum line (5).

2, variable angle wide seating square according to claim 1, its feature is that also the scale on the bevel protractor (2) is 9 to 0 to 9, every little lattice are 5 degree, every big lattice are 10 degree, when datum line on the reference seat (5) alignd with 0 graduation mark on the bevel protractor, bevel protractor (2) became an angle of 90 degrees just with reference seat (1).
